- Release Date : 18.07.1994

- Description
- ~~~~~~~~~~~
- ST.svobject is an external Library-Module for the superplay.library V1+.
-
- It supports reading of ST Modules (SoundTracker V2.4+, ProTracker V2.2a,
- NoiseTracker and compatible Modules).
-
-
- Requirements
- ~~~~~~~~~~~~
- - OS V2.04+ (V37)+ and its libraries
- - for reading of packed modules, either xpkmaster.library or
- powerpacker.library is needed :
-
- Packer needed Libraries
- XPK xpkmaster.library V2+, speficic xpk-compressor libraries
- PP20 a) xpkmaster.library V2+, powerpacker.library V33+
- b) _only_ powerpacker.library V33+
- <None> <no special libraries are needed, but they will simply pass
- through unpacked data modules>
-
-
- Remarks
- ~~~~~~~
- - As with other Players, the filename of the Module has to begin
- or end with the prefix/entension "MOD" ("MOD.module" or "module.MOD")
- - ST.spobject at first tries to use xpkmaster.library.
- If this one is not available, it tries powerpacker.library.
- If none of them is available, it simply uses dos.library :
- So, if you read a packed module, although you did not install any
- decompression libraries, please note the following :
- After loading the data is checked, so that modules which could
- not be decompressed are rejected without any further notice.

- The "powerpacker.library" V33+ is (C)opyright by Nico François.
- The Library is FREEWARE and is needed by ST.spobject, to be able
- to read and play also PP20-packed Modules.
-
- The "xpkmaster.library" V2+ is (C)opyright by its authors
- (c/o Urban Dominik Müller).
- The Library is freely distributable and is needed by ST.spobject,
- to be able to read and play XPK-packed Modules.
-
- Upto V1.2 the main Player Source-Code in Assembler was taken from
- the Public Domain Library "STReplay" by Oliver Wagner, which can be
- found on AmigaLib-Disk #258.
- Oliver said in the Docs to STReplay, that he did not obtain any rights
- to the Source, so I used it for my own purposes.
- Nevertheless I did not just "include" the Source, but made many - more
- or less useful and important - changes to it.
-
- Since V1.3 the new ProTracker V2.2a Player Routine is used.
- I got it from Gerd Frank (thanks Gerd !) and modified it for my own
- purposes : Some changes had to be made to assemble it with the SAS/C
- ASM V6.5 and to make it living in the multitasking better than before.
- Finally, I had to change and add some more code to create an interface
- to the C-SourceCode of the SPObject's main routines.
-
- Here's an excerpt from the SourceCode as far as concerning the original
- authors (no special copyright notice was found, so it is perhaps
- Public Domain) :
-
- * ProTracker2.2a replay routine by Crayon/Noxious. Improved and modified
- * by Teeme of Fist! Unlimited in 1992. Share and enjoy! :)
- * Rewritten for Devpac (slightly..) by CJ.

- History
- ~~~~~~~
- V2.1 (18.07.1994) :
-
- - fixed BAD BUG in file-recognition routine, which may have caused
- this SPObject crashing very often, if
- a) this SPObject was not very late in the list of SPObjects
- b) this SPObject was late in the list, but an unknown
- FileType was selected e.g. in "SuperPlay"
- - integrated new "SampleList"-Functions for exporting more than one
- sample
- - so extraction of samples from modules now is possible
- (see Example-Programs "SampleListDemo" and "SampleListPlay" for
- detailed information on how to use this functions)
-
-
- V1.6 (19.06.1994) :
-
- - added check for Module type "M!K!", which is Noise/ProTracker with
- 100 patterns (thanks to Gerd Frank for reporting this)
-
-
- V1.5 (17.05.1994) :
-
- - use of SAS/C V6.51
- - version still reflected 1.3 instead 1.4. Now we're at 1.5 :-)
- - now "MOD" is either accepted to be the filename's prefix
- ("MOD.ModuleName") or suffix ("ModuleName.MOD").
- This is done, because many modules - e.g. those ported from MS-DOS -
- are named so and we have no other method of identifying them.
- - ST.spobject is no longer dependent on xpkmaster.library :
- now we also use powerpacker.library, if available.
- If no decompression library is installed, we simply try dos.library.
- After loading the data is checked, so that modules which could
- not be decompressed are rejected without any further notice.
- - now checks Module-Type of Files and rejects files, which contain
- IDs other than "M.K." or "FLT4" at the specific offset
-
-
- V1.4 (30.04.1994) :
-
- - version still was V1.2 in V1.3, now we reflect V1.4
- - fixed (hopefully) "header not located" problems within memory
- delocation
-
-
- V1.3 (30.03.1994) :
-
- - replaced old ST Player Routine with new ProTracker V2.2a Player Routine
- - added ST-Module structure definition to Headerfile :
- now it is possible to read the file information without
- playing around with Hex-Offsets.
- - used new STHeader-Definition to print out more information
- about the Module, when calling SPL_FileInfoRequest() :
-
- - SongName
- - Module-Type : "M.K.", "FLT4", ...
- - Number of Instruments (determined by checking InstrLength)
- - Names of Instruments and hidden strings (even if more than
- the nominal number)
- This was a little bit tricky sometimes, but now it works with
- all modules without crashing the Amiga !
- Enjoy reading the "hidden messages" of ST-Files and find out
- the authors of previous "no name"-modules.
- - replaced SAS/C's sprintf()-routine with own, RawDoFmt()-based one.
- This saves about 1800 Bytes.
- - now using Utility-Library for integer operations (activated
- SAS/C's UTILLIB option) : this increases 68000-codesize a little
- bit, but increases speed on 68020+ systems
- (should also decrease codesize, but does not ...)
-
-
- V1.2 (25.02.1994) :
-
- - fixed small bug in memory management routines
-
-
- V1.1 (16.01.1994) :
-
- - first version
